(a) A default YaST printer install uses drivers which are not the "recommended" ones, leading to unexpected results. Obviously, if a driver is "recommended", this should be the one that is installed by default.
Of course it should, see https://bugzilla.novell.com/show_bug.cgi?id=220712
Ah, missed that one - it is relevant with hindsight, but at the time I was focussing on "greyscale". So hopefully that will be fixed in the next iteration.
(b) Changing the printer driver requires a reboot to take effect.
No. Changing the printer driver (i.e. the PPD) or whatever other change of a CUPS print queue doesn't even require a restart of the CUPS printing system (i.e. the cupsd). At any time the admin can run "lpadmin -p <queue> -P </path/to/PPD>" to assign a new PPD (i.e. another driver) to a queue. YaST (and also other print queue setup tools) do equivalent CUPS library calls. I have no idea why in your particular case a reboot was needed.
Yes, I was very surprised, and had it been only one machine, I'd be inclined to say there was an oddity in the hardware. But not with two different machines having the identical problem - this was the only thing that worked on the first, and I then changed the driver on the second a couple of times before trying the reboot. But again, only a reboot worked. So there may be a gremlin somewhere in the code. On Wednesday 12 September 2007 13:29, Joe Morris (NTM) wrote:
Are you sure just rebooting the printer would not have fixed it? I wouldn't think the kernel would be involved in the printer, except maybe usb recognition.
I had earlier tried restarting the printer from cold, but that didn't fix it either. Of course, if a reboot of the printer were necessary, it would still be a good idea to flag that. But as Johannes says, in theory such reboots are not necessary.
